1GENERAL INFORMATION
1.1 Specific features
(1) The long piping makes the location of the inside and units flexible.
¡No need for additional charge of refrigerant : 45 type · 20m, 60 type · 30m, 80 type · 40m
¡Maximum piping length : 45 type · 30m, 60 type · 40m, 80 type · 60m
(2) Connectable indoor capacity
Number of connectable units : 45 type · 2 units, 60 type · 3 units, 80 type · 4 units
Total of indoor units (class kW) : 45 type · 7.0kw, 60 type · 10.6kw, 80 type · 13.4kw
(3) Indoor units are available with 5 capacities.
5 capacities................ 22, 25, 28, 35, 50, 60
Types ......................... Wall mounted type (SKM).
4-way ceiling cassette type (STM).
Ducted type (SRRM).
(4) Inverter (Frequency converter) for multi-steps power control
¡Heating / Cooling
The rotational speed of a compressor is changed in step in relation to varying load, to interlock with the indoor and outdoor unit
fans controlled to changes in frequency, thus controlling the power.
¡Allowing quick heating/cooling operation during start-up period. Constant room temperature by fine-tuned control after the
unit has stabilized.
(5) Fuzzy control
Fuzzy control calculates the amount of variation in the difference between the suction air temperature and the setting temperature
in compliance with the fuzzy rules in order to control the air capacity and the inverter frequency.
(6) Self diagnosis function
We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation as
follows.
